# MS100N03

**MSKSEMI** · MOSFETs · TO-252-2

MS100N03 from MSKSEMI, in a TO-252-2. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate; controls the channel, with VGS rated ±12 V maximum and threshold 0.5 to 1.0 V at 250 µA (MS50N02 data). |
| 2 | D | passive | Drain, also the exposed mounting tab; VDS rated 20 V and continuous ID 60 A (MS50N02 data). |
| 3 | S | passive | Source; continuous body-diode forward current IS is 60 A maximum (MS50N02 data). |
